multiple local IP addresses to one global IP

 

 

 

address. This is equivalent to Many to One

 

 

 

(i.e., PAT, port address translation)

 

 

•

Many-to-Many Overload: This is mode

 

 

 

maps multiple local IP addresses to shared

 

 

 

global IP addresses

 

 

•

Many-to-Many No Overload: This is the

 

 

 

mode maps each local IP address to unique

 

 

 

global IP addresses

 

 

•

Server: This type allows you to specify

 

 

 

inside servers of different services behind

 

 

 

the NAT to be accessible to the outside

 

 

 

world.

Local Start IP

 

This is the starting Inside Local IP Address (ILA). Local

 

 

IP addresses are N/A for Server port mapping

Local End IP

 

This is the end Inside Local IP Address (ILA). If your

 

 

rule is for all local IP addresses, then enter 0.0.0.0 as

 

 

the Local Start IP address and 255.255.255.255 as the

 

 

Local End IP address. This field is N/A for One-to-one

 

 

and Server mapping types

Public Start IP

 

This is the starting Inside Public IP Address. Enter

 

 

0.0.0.0 here if you have a dynamic IP address from

 

 

your ISP

 

Public End IP

 

This is the ending Inside Public IP Address. This field is

 

 

N/A for One-to-one, Many-to-One and Server mapping

 

 

types

 

 

If you have disabled the NAT option in the WAN-ISP section,

 

the Virtual Server function will hence be invalid.

 

If the DHCP server option is enabled, you have to be very

 

careful in assigning the IP addresses of the virtual servers in

 

order to avoid conflicts. The easiest way of configuring Virtual

 

Servers is to manually assign static IP address to each virtual

 

server PC, with an address that does not fall into the range of

 

IP addresses that are to be issued by the DHCP server. You
